英文:
How to delete masked edittext content
问题
以下是您要翻译的内容：
例如："2020/55"，我有一个编辑框，输入四个数字后面跟一个数字，这样就可以正常工作。我的问题出现在删除时。删除“/”后面的部分时，它会显示"/////"，将"/"前面部分的数字作为替代显示。我添加了您的图片，如何删除它。
以及遮罩类
public class CaseInputMask implements TextWatcher {
int uzunluk = 0;
EditText girilenMetin;
public CaseInputMask(EditText girilenMetin) {
this.girilenMetin = girilenMetin;
this.girilenMetin.addTextChangedListener(this);
}
@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
String metin = girilenMetin.getText().toString();
uzunluk = metin.length();
}
@Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
try {
String metin = charSequence.toString();
String girilenDeger = girilenMetin.getText().toString();
if (girilenDeger.length() == 4) {
metin += '/';
girilenMetin.setText(metin);
girilenMetin.setSelection(metin.length());
}
} catch (Exception e) {
}
}
@Override
public void afterTextChanged(Editable editable) {
}
}

英文:
for example: "2020/55" I have an edittext shape, put one after 4 numbers, write a number after it and it works well. My problem starts at the time of deleting. When deleting the part after /, it shows"/////" the figures of the part before / as and instead.I add your picture, how can I delete it.

And mask class
public class CaseInputMask implements TextWatcher {
int uzunluk = 0;
EditText girilenMetin;
public CaseInputMask(EditText girilenMetin) {
this.girilenMetin = girilenMetin;
this.girilenMetin.addTextChangedListener(this);
}
@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
String metin = girilenMetin.getText().toString();
uzunluk = metin.length();
}
@Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
try {
String metin = charSequence.toString();
String girilenDeger = girilenMetin.getText().toString();
if (girilenDeger.length() == 4) {
metin += '/';
girilenMetin.setText(metin);
girilenMetin.setSelection(metin.length());
}
} catch (Exception e) {
}
}
@Override
public void afterTextChanged(Editable editable) {
}
}

你应该这样检查删除操作：
public class CaseInputMask implements TextWatcher {
private boolean running = false;
private boolean deleting = false;
private final String inputMask = "####/##";
public CaseInputMask() {
}
@Override
public void beforeTextChanged(CharSequence charSequence, int start, int count, int after) {
deleting = count > after;
}
@Override
public void onTextChanged(CharSequence charSequence, int start, int before, int count) {
}
@Override
public void afterTextChanged(Editable editable) {
if (running || deleting) {
return;
}
running = true;
int length = editable.length();
if (length < inputMask.length()) {
if (inputMask.charAt(length) != '#') {
editable.append(inputMask.charAt(length));
} else if (inputMask.charAt(length - 1) != '#') {
editable.insert(length - 1, inputMask, length - 1, length);
}
}
running = false;
}
}
还有：
girilenMetin.addTextChangedListener(new CaseInputMask());
英文:
You should check deletion like this:
public class CaseInputMask implements TextWatcher {
private boolean running = false;
private boolean deleting = false;
private final String inputMask = "####/##";
public CaseInputMask() {
}
@Override
public void beforeTextChanged(CharSequence charSequence, int start, int count, int after) {
deleting = count > after;
}
@Override
public void onTextChanged(CharSequence charSequence, int start, int before, int count) {
}
@Override
public void afterTextChanged(Editable editable) {
if (running || deleting) {
return;
}
running = true;
int length = editable.length();
if (length < inputMask.length()) {
if (inputMask.charAt(length) != '#') {
editable.append(inputMask.charAt(length));
} else if (inputMask.charAt(length-1) != '#') {
editable.insert(length-1, inputMask, length-1, length);
}
}
running = false;
}
}
And
girilenMetin.addTextChangedListener(new CaseInputMask())
